| Abstract: | The structure and flora of natural Platycladus orientalis community in Deqin of Yunnan province were studied.The results showed that there were 86 species of seed plants in natural Platycladus orientalis community,belonging to 38 families and 63 genera.The community structure was simple,the number of trees was small,and the species of shrub and herbal plants were few.The results of flora analysis indicated that,9 families showed the characteristics of tropical,and 8 families were obviously the temperate flora.At the lewel of genus,39 genera belonged to the temperate,which was 73.58 % of the total.Many species were Chinese endemic species,and southwest China was the distribution center.Two Chinese endemic genera in natural Platycladus orientalis community in Deqin were Ostryopsis and Psammosilene. |
